Abstract: PURPOSE: To obtain multiple sheets of copies simply through one formation of the latent images of the original by forming the electric signals having been photoelectrically converted after reading the original as magnetic latent images through electromagnetic conversion and transferring and fixing said latent images on paper.  
     CONSTITUTION: First, the latent images of the previous time of the recording drum are erased. Next, photoelectric conversion is accomplished by the operation of the image pickup part to provide the picture signals which are then subjected to electromagnetic conversion, whereby latent image recording is accomplished. The image pickup and latent image recording are accomplished by scanning the original over its entire surface. When the above latent image forming mode is finished, the copy mode is next started, where paper is fed, developed, transferred and fixed, whereby the copy is obtained. On the other hand, the recording drum is cleaned. The paper feeding, developing, transfer, fixing and cleaning are repeated until the number of the sheets of the copies thus obtained reaches a desired number. The operations end upon reaching of the desired sheet number. Since multiple sheets of copies may be obtained simply through one formation of the latent images, the device of less power consumption and superior operating characteristic and maintenance characteristic is provided.

Title: Electron gun structure
Inventor: NARITA KATSUHISA
IPC: H01J29/82
Filed: 1981-08-05
Abstract: PURPOSE:To enable an electron gun structure to be accurately located in the geometrical center of a fluorescent screen by using 4 valve spacer contacts, and locating them at specified spacings so that the sum of their stresses sets of the stress of an antenna-getter supporting member. CONSTITUTION:Four valve spacer contacts 3a-3d are welded to the outer surface of a shield cup 1. Taking into consideration the stress of a supporting metallic member 2a of an antenna getter 2 which is welded and fixed to the outer surface of the cup 1, the spacers 3a-3d are located at unequal spacings so that the spacers 3a and 3b between which the getter 2 is located are at an angle (theta1) of 108 deg., so that the spacers 3c and 3d opposed to the spacers 3a and 3b are at an angle (theta2) of 90 deg., and so that the spacers 3a-3d are symmetrical relative to the Y axis. Owing to the above constitution, when an electron gun structure is installed inside the neck part, the stress of the Y-axis direction caused by the member 2a of the getter 2 is effectively set off. As a result, the stress variation relative to the central position of the structure can be reduced.
